30 Claims.

This invention relates to stitch-regulating mechanism for fiat knittingmachines such, for example, as those employed in the manufacture of fullfashioned hosiery or in any instance where needles are bodily movable toand from a cooperating bank of successively operable sinkers forregulating the length of the stitches produced by the needles.

One object of the'invention is to provide -a novel stitch regulatingmechanism that is flexible and universal in operation, and which permitsan infinite variety of pattern effects to be obtained in any part of thestocking fabric.

Another object of the invention is to provide an efficient mechanism forrocking the needles to various positions with respect to the projectedposition of the sinkers and to maintain such relationship between theneedles and sinkers throughout the whole or any part or parts of anysingle sinker-traversing movement of the slur cock, for lengthening thestitches of a full course or any part or parts of a single course orseries of successively knit courses, for producing, for example, asingle loose course or plurality of immediately succeeding loose coursesat the turning line of a double welt full fashioned stocking, or informing a picot edge at the turning line of the welt, or in providingtopping lines in the heel tabs of a. full fashioned leg blank, or forlengthening single stitches or groups of stitches in a singlecourseorsuccession of courses where a design is being formed by theintroduction of an additional thread with the main thread, orlengthening predetermined stitches in the high splice heel to providefor the introduction with the normal main and splicing threads of athird thread adapted to provide additional reinforcement at localizedpoints or areas in the heel of the stocking.

Another object of the invention is the provision of simple and efficientmeans for controlling the selection of the stitches to be lengthenedandthe positioning of the lengthened stitches with re- :pect to the selvageedges of the fabric, whereby the outline of the area or areas whichinclude the lengthened stitches will coincide with the marginal edges ofdesign areas produced by the additional thread or threads above noted,wherein the marginal edges of the areas including the additicnal threadsare governed by the thread carrier controlling mechanism of the machineor by a separate attachment applied to the machine.

More specifically, this feature of the invention involves the provisionof a stitch-regulating chain or drum or a combination of the twocomposed of or equipped with readily detachable and interchangeablelinks, lugs, lobes, or other variable protuberances or surfaces ofvarying height or radii arranged and adapted to rock the normalstitch-regulating shaft of the machine to effect selective lengtheningof the stitches. I

Another object of the invention resides in the provision of novel meanswhereby the lengthening of stitches may be produced symmetrically at thecenter of the stocking blank and/or at corresponding points at each sideof thev longi- 10 tudinal center line of the blank, and in any desiredposition.

A further object is to provide a device of the character described whichis relatively simple in construction, and which may be made as an at- 15tachment readily applicable to straight knitting machines ofconventional type, and which makes possible the production on suchmachines of a variety of products heretofore not producible thereon.

With these and other objects inview, which will become apparent from thefollowing detailed description of the illustrative embodiments'of theinvention shown in the accompanying drawings, myinvention resides in thenovel elements 25 of construction, mechanisms and combination of partsin cooperative relationship, as hereinafter more particularly set forthin the claims.

The figures disclose various parts of a Reading full fashioned knittingmachine embodying the invention, in which for clearness, only the partsnecessary to an understanding of the invention are illustrated; theother parts, and the operation thereof, being well known in the art asshown and described in the Reading" Full Fashioned Knitting MachineCatalogue, copyright 1929, and published by the Textile Machine Works,Reading, Pennsylvania.

In Figs. 1, 2 and 3, the machine to which the mechanism of the presentinvention is applied for the purpose of illustration is illustrated asbeing of the type employed for producing full fashioned hosiery, whichcomprises a front beam a back beam 2, a center bed 3 and a front bed 4,extending parallel to each other longitudinally of the machine andrigidly secured to transverse end frames 5 and center frames 6, 6.Machines of this type include a plurality of parallel longitudinallyslidable thread carrier bars 1 which respectively carrythread-controlling fingers 8 for laying individual threads between thesinkers 9 and needles ID of the machine.

The needles are rigidly mounted in a needle bar II which is pivotallymounted at |2 in relatively spaced arms l3. The arms |3 are secured to alongitudinally extending needle bar shaft M which is adapted to berocked for raising and lowering the needles by the usual cam and levermechanism from the main cam shaft l5 of the machine.

The position of the needles l0 relative to the throats or shoulders |6of the sinkers, when the sinkers are in their most forwardly projectedposition, determines the length of the stitches and is controlled orgoverned by rocking the needles In about the pivots l2, toward thesinkers for lengthening the stitches and away from the sinkers forshortening the stitches.

The position of the needles relative to the foremost position of thesinker shoulders H5 is normally controlled by what is termed thestitchregulating shaft of the machine, which in the present instance isillustrated at 20 in Fig. 3.

In the present instance, the mechanical connections between thestitch-regulating shaft 20 and the needle bar II are of the usualconstruction, such for example as shown in the patent to C. F. Meyer,No. 1,694,888, dated December 11, 1928, said patent showing continuouslyrotating cam mechanism whereby the stitch-regulating shaft 20 isnormally rocked toward the sinkers for lengthening the stitches in, andduring, the formation of the high splice heel reinforce and heel tabs.

The sinkers 9 in the present instance are projected by the usual jacksI9 which are operated by a slur cock |8 arranged to make a completesinker-traversing movement for each course of stitches produced. Theslur cock is, as usual, operated by a bar I! which is connected to theCoulier motion of the machine in a usual manner.

In the present instance, selective rocking of the stitch-regulatingshaft 20 is accomplished by the following mechanism:

Secured to the stitch-regulating shaft 20 (see Fig. 3) is ashaft-actuating or stitch-regulating lever 2|. The stitch-regulatinglever 2| is provided with a laterally extending stud 22 on which isrotatably mounted a roller 23. The roller 23 is adapted to be movedlongitudinally of the stud 22 into and out of the plane of a selectorchain 25, by means of a control lever 24.

The selector chain 25 includes a. plurality of readily detachableinterchangeable links 35 each having an outer variable cam surface orconvex edge 26 shaped in accordance with the selections that therespective links are to make of single stitches or groups of stitcheswhich are to be lengthened in successive individual coursesrespectively.

The inner surfaces 21 of the links are concave and uniform, each linkhaving a pair of relatively spaced lugs or feet 28 arranged to rest onthe peripheral surface 29 of a drum 3!] which is loosely mounted on thecam shaft |5 of the machine.

The drum 3!! is provided with side flanges 3|, 3| between which thelinks 35 are disposed and which are notched at 32 to receive laterallyextending ends of the pintles 33 by which the links 2,014,100 35 of thechain 25 are pivotally connected to each other.

As illustrated in Fig. 21, each link 35 is provided with a tongue 36 ofreduced width at one of its ends which projects into a slot formed byand between a pair of parallel ears 34, 34 projecting from the oppositeend of the adjacent link, the ears and tongues of the interconnectedlinks be.-

ing bored at 38, 38 respectively for the reception groups of stitchesare to be lengthened and theof the pintles 3 The length of the chain 25is determined by the number of courses in'which different single ororder in which such variations occur.

The outer end of the chain 25 is carried by a drum 39a. The drum 30a isrotatably mounted on a stud 39 which is carried by a bearing or block 40adjustably mountedon, and for longitudinal movement with respect to, alaterally projecting arm 4|, the inner end of which is secured in abracket 42 which in turn is suitably fixed to the back beam 2 of themachine.

The drum 39 is adapted to-be intermittently rotated to bring the links35 of the chain 25 successively into operating relation to the roller 23of the stitch-regulating lever 2| and for this purpose the drum 39 isprovided with a plurality of teeth, which in the present instance areformed of pins 43, 43, as "shown in Fig. 5, which project laterally fromone side aged by a pawl 44.

of the drum, to be en- The pawl 44 is pivotally mounted at 45 on a lever46 which is pivoted at 41" to the bracket 42.

Rotatably mounted on a stud 48 which extends transversely of the lever46 is a cam roller 49, as clearly shown in Fig. 10, which is adapted tobe engaged by a cam 50 secured to the main cam. shaft |5 of the machine.

Normally the drum 30 is held against rotation by a locking bolt 5| (seeFig. 6) which is slidably mounted in abearing 52 beam I. The outer end53 is tapered for entrance shaped notches 54 formed in a locking disc 55that is secured to the drum by thepins 43 which have integral nut-likeheads 56.

The locking bolt 5| is normally held in looking engagement with the disc55 by means of a spring 51, one end of which is secured to a pin 58secured in, and projecting laterally from one side of, the bearingbracket 52, while the opposite end of the spring is secured to pin 59which extends through, and is secured in, the locking bolt of thelocking bolt 5| 5| and extends through slots 69, 66 formed. in the ondarm 65 of the bell-crank lever is provided with a laterally extendingstud 66 which is disposed in an elongated slot 61 formed in one end ofan operating link 68, the opposite end of said llnkbeing pivotallyconnected at 69 to.the pawl Normally, as the cam 58 revolves with thecamshaft IS the by the cam 59 and in-the opposite direction by a spring 10,one end of which is secured to the free end of the lever 46 while theopposite end is suitsecured. to the front into correspondingly lever 46is rocked in one directionably secured to the front beam of the machine.Normally the pawl 44 assumes the inefi'ective position shown in Fig. 3,during the rocking of the lever 46 while normal regular courses ofstitches are being produced. I

As usual in this type of machine, a pattern chain 1 is provided forcontrolling the narrowing of the blank and other functions of themachine, the pattern chain "H advancing one link for each course ofstitches produced, or one link for each 10 complete revolution of thecam shaft l5.

In the present instance the pattern chain H is provided with a series ofbuttons 12 spaced along the chain in accordance with each single courseor with the first course of a group of identical 15 courses which are tobe composed wholly or in part of lengthened stitches under control ofthe mechanism forming the subject matter of the present invention. i

In the present instance, the buttons 12 are 20 adapted to engage a lug13 formed on a lever I4 which is pivoted at 15 to the pattern chainbracket 16, said bracket being rigidly secured to the front beam Thelever 14 is connected by a link 18 to one end of a lever 79. The leverI9 is pivoted 25 at to the pattern chain bracket 16.

The second end 8| of the lever 19 is operatively connected to one end ofa rod 82 which extends substantially parallel to the front beam Theopposite end of the link or rod 82 is operatively 30 connected at 83 toone end of a lever 84. The lever 84 is pivoted at 85 to the drum-lockingbracket 52. 1 v

The second end 86 of the lever 84 is provided with the spring-pressedstop 81 shown in detail 5 in Fig. 7, the stop 81, being provided with astem 88 slidably mounted in a bearing 89 formed in the one end 86 of thelever, a spring 96 being confined between the'head 8'! and the bearing89 and a collar 9| being secured to the stem 88 at the op- 40 posite endof the bearing 89 for limiting the movement of the stop 81 with respectto the lever end 86.

At such timeas intermittent movement of the drum 39 is desired one ofthe buttons 12, by 45 engaging the lug 73 of the lever 14, swings thelever 84 about its pivot 85 to bring the stop 81 into the path of afinger 92, see Fig. 4, formed on the pawl 44, whereby, as the pawlinglever 46 is swung outwardly by the cam 59, the finger 92 comes in 50 acontact with the stop-81 and swings the pawl 44 about its pivot 45 untila shoulder 93 on the pawl 44 rests against one of the pins 43 of thedrum 3D.

Swinging of the pawl into engagement with one 55 of the pins 43 effectswithdrawal of the locking bolt 5| from the occupied notch 54 of thelocking disc 55. through the link 68, bell-crank 6563 and link 5|, suchposition of the elements being clearly illustrated in Fig. 13.

Further rotation of the cam 5|! permits the lever 46 to rock toward thecam shaft I5 under the influence of the spring 18, that is, from theposition shown in Fig. 13 to the position shown in Fig. '14, whichcauses the pawl 44 to eifect a single step movement of the drum 30 aboutthe axis of the cam shaft l5.

During such pawling movement of the lever 46, and due to the relation ofthc pivotal connection 69 of the link 68 to the rotation of the lever 46and the elongation of the slot 61 in the line 68, the locking plunger5|, under the infiuenceof its spring 57, first engages and then slideson the peripheral surface of the looking disc 55, and, as the pawl 44attains its max- 75 the lever 2I is moved,

regulating shaft shoulders I of the directionduring the remaining of theblank the link ,radially with respect to the metrically governed imumposition, the tapered end 50 of the locking plunger'5l snaps into thethen aligned notch 54 of ,the disc 55 and prevents further rotation ofthe drum 50.

when the spring pressed stop 01 is moved out of operative relation tothe finger 92 of lever 44 by means of the pattern chain 'II, and the camroller 49 of lever 46 rides over the high portion of cam 00 the lever 44assumes the position as shown in Fig. 15. At this time the plunger 5I,through the action of link 6 I bell crank. 65 and 63 and the link 6 Iwill be only slightly withdrawn from the notch 04 of locking disc 55 soas to prevent rotation thereof. v

Such movement of the drum 30 brings one of the stitch-lengthening links05 into operative relationto the roller 22 on the stitch-regulatinglever 2|. The cam surfaces 26 of the links 35 do not function directlywith the roller 20. Rocking of the lever 2I is effected by" anintermediate mechanism comprising a shoe I00 (see Figs. 8, 9, 11, i2 and18). V

g The shoe I00 is provided with a foot IOI which is slidably mounted ina lever I02 for movement axis of the main cam shaft I5 upon which thelever I02 is loosely mounted. A spring I00, having one end attached tothe foot Ill and the opposite end attached to the lever I02,- tends tomovethe shoe I00 inwardly at all times- Rotatably mounted on a stud I04,which proiects laterally from the foot iIOI, is a roller I05 which isadapted to ride the cam surfaces 26 of the links. 05 of the selectorchain 25, whereby the shoe I00 is moved outwardly and inwardly or viceversa as the lever I02 is rocked about the axis of the shaft I5. Duringsuch time the drum 30 with the chain 20 thereon is held in a relativelyfixed position. k

The outer-peri' heral surface I00 of the shoe I00 is formed on an arcstruck from the axis of the shaft I0, and the roller 23 on thestitch-regulating lever 2| bears against the arcuate surface I00 of theshoe I00, and as this surface is moved radially outwardly or inwardly,in accordance with the contour or variable heights of the cam surface 20of the link 00 which has been positioned in operative relationship tothe lever 2|,

and consequently. the stitchto throw the needles sinkers 0, forlengthening the stitches or for returning the needles to a position forthe formation of regular stitches, as the case may be.

The rocking of the shoe I00 with respect to the roller 20 .is concurrentwith the traversing of slur cock I0 and in order that the stitches willbe symthe shoe I00 rocks in one first half of the traversing and in anopposite half of the travof said slur cock. consequently, in cases wherethe lengthening of thestitches is to be effected at, or immediatelyadjacent to the center of a course of stitches the cam surface 20 of thelink in position will have a rise only at one end of the link. If thelengthened stitches are to be produced adjacent to the selvage edgesimposition will have a rise at the opposite end of the link. Iflengthened stitches are to be produced bot-bends of acoursethelinkinposition willbe provided with a rise at each end, the length of thedirection during the movementof the slur cock I0 ersing movement ispivotally connected to the lever is correspondingly moved l0 toward oraway from the at the center and at each instance. Obviously,

- the locking 35 then in position a it drops onto and risecircumferentially of the drum 30' determining the number of stitches tobe lengthened in where the lengthening of the stitches occursintermediate the center line of the blank and the selvage edges of theblank the rise in the link will accordingly be positionedcircumferentially of the drum. The height of the rise determines theextent of rocking of the needles and consequently the extent of thelengthening of the stitches. In cases where the stitches'are to belengthened throughout a full course, the rise of the surface 26 of thelink in position, and which corresponds to that particular. course, willextend from end to end of the link. In this manner the lengthening ofindividual stitches or groups of stitches in any place in any course anddisposed symmetrically at each of the opposite sides of the center lineof the blank may be effected.

The rocking of the shoe I00 is effected by the samemechanism whichaffects the intermittent rotation ofthe drum 30, the'first part of themovement of the lever 46 being adapted to provide the pawling movementwhile the remainder of the stroke of the lever 46 is adapted to provide25. the rocking motion of the shoe I00 across the cam surface 26 of thelink 35 which has just been moved into operative relation to thestitch-regulating lever 2|, the last part of the inward stroke of thelever 46 and the first part of the outward 30 stroke of said levertaking place concurrently with the first and second halves respectivelyof the full sinker-traversing movement of the slur cock I8. I

The shoe-carrying lever I02 is provided with an arm I01 to which ispivotally connected at I08 one end of a link I09, the opposite end ofwhich 46 by bein mounted on the same stud 45 that provides the pivotalconnection for the pawl 44 with the lever 46.

The peripheral surface of the cam 50 which effects the pawling orintermittent movement of the drum 30 and also the rocking motion of theshoe I00 is so cut that,- after the drum 30 has been rotated thenecessary distance to permit bolt 5| to enter one of the notches 54 ofthe disc 55 to hold the drum in position, the lever 40 receives a slightbackward movement sufflcient to release the pawl 44 from the tooth orpin 43 of the drum 30 by which such movement of the drum has beeneffected, after which renewed and continued forward movement of thelever 46, for rocking the shoe I00 past the link and the roller 23 onthe stitchregulating lever 2I is eflfected.

As soon as the pawl 44 is released from the pin slides over a shoulderIIO,

formed on the locking bracket 52, throughout the remainder of theforward movementof the lever n 46 and during return movement of saidlever to the position shown in Figs. 3 and 8.

In producing ablank, such as that illustrated in Fig. 16, the bodyportion A of the blank, down to the line a, a, is knit in the usualnormal manner. The link 35 then in operative relation to thestitchqregulating lever 2| is of such height throughout its entire length asnot to effect the normal length of stitches of which the body portion Ais composed, the length 'of said stitches being regulated 7 0, by thenormal stitch-controlling mechanism of the machine.

During the last part of the knitting or the course of stitchesimmediately. preceding that represented by the line a, a the patternchain It ders I5 of the sinkers 9 and being will advance to bring one ofthe buttons 12 thereon under the lug I3 of the lever 14, wherev plunger5| is simultaneously withdrawn from the occupied notch 54 of the lockingdisc 55 of said drum. The roller 49 of the lever 46 will then ride onthe high portion 501; of the cam with the spring 10 stretched to itsmaximum extent. As the cam 50 continues to rotate the roller 49 ridesdown the incline 50b of the cam and the spring 10 at the same time rocksthe lever 46 toward the cam shaft l5, from the position shown in Fig. 13to the position shown in Fig. 14, whereby movement of the drum to theextent of one step is effected and by the link shown, for example, inFig. 17a. The locking plunger 5| at the same time is reseated in one of-the locking notches 54 of the disc 55.

Continued rotation of the cam 50 brings a rides down the incline 50dthereof and the spring 10 rocks thelever again towardethe shaft I5. Inso doing the lever I02 is rocked to bring the leading point |00a of theshoe I00 into engagement with the roller 23 of the stitch-regulatinglever 2| as clearly shown in Fig. 8.

The roller I05 of the shoe I 00 rides onto the high point 26a of thelink 35 at substantially the same time as the point |00a of the shoe I00 engages the roller 23 of the stitch-regulating lever 2|, whereby thestitch-regulating shaft 20 is rocked and the needles I0 arecorrespondingly rocked toward the sinkers.

The slur cock I8 then begins its travel across the sinkers, to sink thethread around the needles for the first course of stitches included inthe high splice heel reinforce B.

During the travel of the slur cock across the sinkers and during thesinking of the yarn thereby, from the selvage A to the inner line B ofthe reinforce B, the lever I02 is being rocked and the roller I 05 ofthe shoe I00 is riding on the high part of the link, from the point 26ato the point 26b, whereupon the roller I00 rides onto the normal portionof the link 35, permitting the stitch-regulating shaft 20 to rock backto the corresponding to the center line 1:, a: of the blank, the needlesI0 rocking outwardly from the shoulheld in such position during thetravel of the slur cock across the sinkers to the center of the bank ofneedles.

During such movement of the slur cock I8 the lever I02 has continued torock, in a counterclockwise direction, as viewed in Fig. 9, by reason ofthe roller 49 riding down the incline 50e of the cam 50 under theinfluence of the spring 10, until the roller reaches the low point 50fof said cam, the shoe I00 during such rocking of the lever 46 rockingaround the shaft I 5, altho at this time not controlling the length ofthe stitches being produced, the limit of travel of the shoe beingdetermined by the contour of cam 50 and ordinarily being such that thesecond end I 00b thereof is the plain link is replaced- 'for examplethat of 5 adjacent to the roller 23 of the stitch-regulating lever 2|.

During the travel of the slur cock I8 past the second half of thecomplement of sinkers,-corresponding to a movement from the center linew, a: of the blank to the" selvage A shoe I00 is rocked in an oppositedirection by the roller ersing movement from the inner line B of thehigh splice heel B until the selvage A of the blank is attained.

It will here be the carrier bars I to the needles are noted that themovements of by which the threads being laid selvages A and A During theabove noted single traversing mover ment of the slur cock l0 the patternchain 1| has advanced one link, to remove the button I2 from under thelug of the lever I4 whereby the rod 82 is shifted in an oppositedirection to re- 1 move the stop 81 from the path of the finger 92 ofthe pawl 44, consequently there will be no movement of the drum 30during the next cycle of rotation of the shaft I5 and the link then inoperative relation to the stitch-regulating lever for the knittingoutwardly and inwardly as the roller I05 thereof is rocked across thecam surface 26 of the link in position, between the end point. 26a ofsaid cam surface which corresponds to the selvage edges of the fabricand the end point 260 of the cam surface which corresponds to the centerline 3:, :c of the blank.

Fig. 17b, into operative relation to the stitch-regulating lever 2|.This link is similar to the link shown in Fig. 17a, with the exceptionthat it includes a second elevation in dicated by numerals 26d and 26e,the cam surface 26 of the link between these points being of higherelevation relative to the axis of the cam shaft I5 than the cam surfacebetween the points 2611 and 20b of the link shown in Fig. 17. Thishigher elevation effects a greater rocking of the needles I0 toward theshoulders I6 of the sinkers 9 to slightly increase the length of thestitches in the courses from the sel-vage edgesA and A of the blank tothe inner lines or edges C and C of relatively thickened areas C and Crespective ly, in which a third thread is incorporated in addition tothe splicing threads knit into the areas B and B The operationthroughout the knitting of the main body thread and the single I 6courses between the lines D, b and c, c is the same as the operationsduring the knitting of the courses between the lines a, a and b, b withthe exception that the drum 30 is moved, for ex- 5 ample after eachfourth course, then after each third course, then atter each secondcourse and finally after each course, bringing the links of Figs. 17c,17d, l'Ze, 1'7], 17g, 1771,1711 and 171i successively into operativerelation tov the stitchregulating lever 2 I, the difference in each ofthese links being that the points 261) and 26a are moved closer to thecenter point 260 in progressively increasing steps, whereby the innerlines B and C and B and C of the areas B and B C and C respectively arecaused to extend at an angle or to be curved with respect to the centerline of the fabric.

During the knitting of the courses between the lines 0, c and d, d thelink shown in Fig. 1'1 remains inoperative relation to thestitch-regulatinglever2l.

- From the knitting of the course corresponding to the lined-d to theknitting of the ends of the heel tabs indicated by the line e, e thelength of the stitches'in the heel tabsD, D is controlled by a linkhaving a uniform height from end to end corresponding substantially tothe high portion of the link shown in Fig. 17a. During the formaplainsurface ofeven height from end to end, so as not to interfere with thenormal stitch-regulating mechanism, is moved into operation relative tothe stitch regulating lever 2|.

In producing the blankshown in Fig. 19 the link of Figs. 20a and 2011having elevated portions 26! of different lengths at the end 260 of thelinks are employed in succession and duplicated in reverse order toproduce the upper central design area E, then a plain non-elevated linkso that the production of the portion A of the blank A may be controlledby the normal stitch regulating mechanism. Then the links of the kindshown in Figs. 20a to 20 are again employed to produce the upper part ofthe lower central-design area E after which links of the character shownin Figs. 20a to 20i, having variable elevated surfaces 26a intermediatetheir opposite ends in addition to the variable elevated surfaces 261 attheir ends 26c, are provided to produce the lower part of the lowercentral design area E and the upper tapering parts E, E of the highsplice heel areas, and the links 20h to 2011. are used to produce thelower parts E, E of the high spliced heel areas.

The links of Figs. 20a to 20ft are shown in cooperative relation to shoeI which is rocked by a cam i0 as shown in Fig. 22. In producingsuchareas e link may be cut to provide a dwell of the roller I05 on the camsurfaceof the link during the movement of the slur cock the sinkerscorresponding in position to the plain portions of the blank between theside and central design areas and to provide a .quickened action of theshoe roller over the portions of the link-elevated surfacescorresponding to the central and side design areas, for more accuratelycontrolling the lengths of the stitches in the more or less rapidchanges from long to.

satire stitches and vice ver In producing theblank shown in Fig. 23 withdesign areas of variable widths between each of the side edges of theblank, such as clocks, etc., as indicated at a in said figure, links ofthe type shown in Figs. 24a. to 24h are provided in 7 forward andreverse order in the chain 20, each and means for moving link havingonly one elevated surface 26g between its ends, and the surfaces of thelinks being of 25 for operating the shoe I00 in relation to the links,Figs. 24a. to 2411..

In order to produce'full courses of lengthened stitches, as at the picotedge F, welt juncture G,

and topping lines H in the blank showlfin Figs. 26

and 27, the surfaces 26h, 26f and 261' of the links in Figs. 28, 29 and30 respectively are employed.

These surfaces extend uniformly from end to end the surface of the linksand vary in height only, 267 of the link in Fig. 30 being only slightlyhigher than the normal length stitch height indicated by the broken liney, y for producing looping lines such as the lines H, H in the heeltabs. The surface 26i of the link shown in Fig. 29, is but slightlyhigher than the surface 267, for forming the picot of the line Y-Y isprovided, for the reason hereinbefore stated.

From the above, it will be clear that by producing links having "camsurfaces of various heights and various lengths and by placing theseelevated cam surfaces at various places throughout the length of thelinks, or along the whole of the length of the link, stitches at anyplace in any course throughout the knitting of the stocking blank fromend to end thereof may be selectively lengthened to any desired extentin conjunction with the normal operation of the machine.

Of course, the improvements specifically shown and described, by which Iobtain the above results, can be changed and modified in various wayswithout departing from the scope of the invention herein disclosed andhereinafter claimed. L
